HENRY LANG, OF ALBANY, AND EDWARD J. WATSON, OF TROY, NEW YORK; SAID WATSON ASSIGNOR TO SAID LANG.

PRINTING-STAMP.

SPECIFICATION forming part of Letters Patent No. 381,880, dated April 24, 1888.

Application filed September 6, 1887. Serial No. 249,930. (No model.)

To all whom it may concern:

Be it known that we', HENRY LANG, of the city and county of Albany, and EDWARD J. WATSON, of Troy, in the county of Rensselaer, both in the State of New York, have invented new and useful Improvements in Printing- Stamps, of which the following is a specification. n

Our invention relates to improvements in printing-stamps that are more particularly designed for office use; and the object ot' our invention is to provide a simple and efficient apparatus for the purpose named. This object we attain by the mechanism illustrated in the accompanying drawings, which are herein referred to and form part of this specification, and in Which- Figure 1 is a longitudinal section of our stamp adjusted to print from an ordinary thin india-rubber type-plate; Fig. 2, a similar section (at the line' x x on Fig. 3) of our stamp adjusted to print from india-rubber type; Fig. 3, a plan view of the same; Fig. 4, a transverse section of the impressionpad, and Fig. 5 a like section of the inking-pad.

As represented in the drawings, A is the metallic bed-piece of the stamp provided with perpendicular standards 1, which are erected at or near the opposite ends of its median line. Said bed-piece is also provided with a perpendicular standard, 2, which is erected at one corner, preferably at one of the corners adjacent to the inking-pad.

B represents the impressionlevers, which are pivoted, as at 3, to the standards 1, so as to range parallel with each other. Said levers are connected together at their free ends by a crosshandle, 4, so that they will move as one piece. Said bed-piece is provided in the recesses of its upper face with spurs a for holding the ink and impression pads hereinafter described.

O is the platen which carries the typeplate and which is provided on its upper face with arms 5, by which said platen is suspended from a transverse rod, 6, whose opposite ends are held in the impression-levers B, the arms 5 being fitted to the rod 6, so that said arms will hang pendently from said rod, the latter serving as a pivotal center on which the platen C swings. Said platen `has on its upper face, ad-

joining the inner side of one of the arms 5, but at right angles to the latter, a lug, 7, which is bored to slide ou a vibratile steadying-bar,

8. The latter is pivote'i at one end to an arm, n 9, that is adj ustably secured to the standard 2 which clasp the beveled edges of the platen C,

so that said spring-fastener and its attached type-pallet may be readily detached from said platen.

F is the inking-pad, which consists of a thin quadrangular block of wood, which is covered by thicknesses of cloth or felt 11, whose edges are turned over and secured in grooves 12, formed in the edges of the wooden blocks. Metallic wires 13 are cemented in said grooves at the end-grain edges of said block, which wires serve the double purpose of securing the thicknesses of cloth and preventing the block from warping.

G is the impression-pad, which consists of a thin quadrangular block of wood having on its upper face an elastic cushion,14, ofi ndia-rubber or other suitable material. Said block has, in opposite edges, at the end of the grain, grooves in which metallic wires 13 are cemented for the purpose of preventing the pad from becoming warped. Removable guide-'stops' l5 are inserted in said pad for the purpose of accurately locating the place where the card or other article to be printed is to be fixed.

The operation of our stamp is as follows: The type-palletE being fixed on the platen C, and the inkingpad F having its felt sufficiently saturated with ink, the card or other article to be printed is flxed in the required position on the impression-pad G. The type-pallet E is brought in contact with the upper face of the inking-pad F, so that the face of the letters will receive a sufficient coating of ink. Then by swinging the impression-levers B toward theimpressionpad G, the platen C, and

itsattached type-pallet E, is carried into posiopposite end an impressionpad, mpression- 15 tion to imprint the impression of the letters levers pivoted to sadbed-piece,so asto vibrate on the Gard on the impression-pad. The platen C is brought to an exact horizontal position at 5 each end ofthe movements ofthe impressionlevers B, and is prevented from acquiring a swinging motion by the steadying-bar 8, whose function is to steady said platen. W'hen preferred, said steadyingbar may be dispensed 1o with, and the stamp Will then operate as well but not as rapidly as with the steadying-bar.

We claim as our invention- A printing-stamp consisting of a bedepiece having at one end an inking-pad and at the to each of said pads, a platen carrying a typepallet pendulously attached to said impressionlevers, a steadying-bar which passes through alug on said platen andis pivoted to a pendu- 2o lons arm that is adjustabiy attached to said bed-piece, all constructed and arranged to operate as herein specified.
